RAILWAY CAR noon AND POST STRUCTURE Fil ed Sept. 5 1942 2 Shets-Sheet 2'INVENTGR; AXEL WASBERG Patented July 23, 1946 V '1" OFFICE RAILWAY CAR.nooaANn POST STRUCTURE Axel Wasberg, Chicago, Ill.', assignor to ChicagoI Railway Equipment Company, Chicago, 111., a corporation of IllinoisApplication September 5, 1942, Serial No. 457,405

The invention relates to the formation of a weather excluding seal atthe forward edge of a sliding door, when the door is closed, such as isadapted to be used effectively on railway box or house type freight carswhere the exposure to winds and currents of air set up by the movementof the car tend to drive rain, snow, dust, cinders and other foreignmatter to the interior of the car with likely damage to the lading.

In Patent No. 2,226,419; issued to the present applicant December 24,1940, the front edge of the door and the adjacent postcooperate to forma pair of successive weather pockets opening towards the exterior of thedoor andserving to ba'flle inwardly moving currents of air and trapdirt, water, etc., carried thereby.

The general object of the present invention is to provide a moreeffective weather seal at the front edge than that disclosed in' theabove-mam tioned patent. One way of obtaining this object is byutilizing a flexible weather-strip element in association with rigidelements on the door and post to cooperate therewith in forming theweather excluding pocket. Another way of obtaining this general objectis to have spaced metal elements of the post and door structure providea third pocket facing outwardly of the car cooperating with successivepockets. as previously disclosed. This general object may be obtained bycombining the flexible weather-strip element and the third pocketforming structure.-

Thedoor panels 8| and 82, auxiliary door post 83, auxiliary door edging andmaindoor stop 84 and angular member 85 are. substantially identical withthe corresponding parts shown in Figure '7. The flexible weather-stripmember 86 is secured between members 83, 82 and 84 and has a reversecurve projecting portion arranged to be engaged by the oifset' andoutwardly bent forward flange 81 of the door front edge member 88. Thisarrangement provides an outer pocket Q, an inner pocket R and anintermediate pocket S functioning as do the triple pocket arrangementpreviously described.

Figure 9 corresponds generally to'the arrangement of Figure 4 butshows'the parts embodied in the main door and auxiliary door joint of adouble door structure. The post main member 9|, the inner rigid angularmember 92, the door front edge member 93 and the door stop member '94are substantially the same as the corresponding members shown in Figures'7 and 8 except that the inclined forward flange 95 of the door edgemember is straight. The intermediate member 96 is rigid and is shaped toprovide extended contact with flange 95. Insofar as the member 96 isrigid the structure corresponds to that shown in Figure 4. As in theother forms of the invention, three successive pockets T, U and V areformed to block incoming currents of' air and trap dirt and moisturecarried thereby which will be drained downwardly to the bottom of thedoor and post.

Each form of the invention attains the general object described in theintroductory portion of the specification in different specific embodiments, and it is to be understood that, so far as the presentinvention is involved, it is immaterial whether the post cooperatingwith the front edge member of the door is a post forming a fixed part ofthe car body or is a post mounted on an auxiliary door. The difierentarrangements shown in the drawings are intended to be illustrative andspecific features of the body post and associated door may be embodiedin the auxiliary door post and associated door and vice versa, as may bedeemed expedient. Some of the elements may be omitted, leaving twopockets embodying novel features of the construction. Other variationsin details of construction may be made by those skilled in the artwithout departing from the spirit of the invention, and the exclusiveuse of such modifications as come within the scope of the claims iscontemplated.
